What I tried the other day was measuring my ping with speedtest.net using a mobi and then re-did it, but this time I used ultravpn, which seemed to decrease the delay. I didnt quite get why did this happen, Ill be posting pics later to see if it happens again.
First test using my regular unmodified connection with mobi
Now using my mobi with ultravpn
there is a decrease of around 300ms on average.
